The American Award for Horse of the Year, one of the Eclipse Awards, is the highest honor given in American thoroughbred horse racing. Because Thoroughbred horse racing in the United States has no governing body to sanction the various awards, "Horse of the Year" is not an official national award.[1]

The Champion award is a designation give to a horse, irrespective of age, whose performance during the racing year was deemed the most outstanding. The list below is a Champion's history compilation beginning with the year 1887 published by the Thoroughbred Owners and Breeders Association's The Blood-Horse magazine (founded 1961),[2] described by ESPN as "the Thoroughbred industry's most-respected trade publication".[3]

In a rare occurrence, two two-year-olds topped the balloting for 1972 American Horse of the Year honors with Secretariat edging out the filly, La Prevoyante. Secretariat received the votes of the Thoroughbred Racing Associations of North America and the Daily Racing Form, while La Prevoyante was chosen by the National Turf Writers Association.[1]
